Heavy rains contribute to weathering by saturating the ground and potentially expanding cracks, which helps *loosen* the boulder or the material supporting it. Heavy rains also act as a trigger for mass wasting by increasing the weight of the material, reducing friction (lubrication), and increasing pore water pressure. Erosion by the heavy rain could also potentially undercut the boulder&#8217;s support. The actual *movement* of the boulder downhill under the influence of gravity is a clear example of mass wasting (potentially a rockfall or part of a landslide).
